Description
Technical field
The present invention relates to LED screen technical field, more particularly to a kind of telescopic LED screen based on set square.
Background technology
The existing LED screen product of in the market has a lot in scenes such as advertisement, exhibition, sports meet and theatrical performances
Using, but be all fixed mask size, this application for causing the such scene of large-scale concert, the Olympic Games big is restricted.Example
Board of calling the score such as Winter Olympic Games is fixed LED screen, is seen clearly under snow mountain, but Chu is not seen on snow mountain.
Existing LED screen is all fixed dimension, and the size of curtain wall can not change, because the size of screen can not become,
So that closely see it is remote see effect difference, such as closely see can with image far see it is just too small, far see can with it is near see then anamorphose, this
Outer carrying installation is also very inconvenient.
The content of the invention
It is an object of the invention to solve the above problems to propose a kind of telescopic LED screen based on set square, it can be with
Control changes the size of curtain wall itself so that curtain wall stretches manyfold, after LED is embedded in thereon, can turn at night
The advertisement screen of variable-size, screen size is flexible to cause distance all to see clearly.
In order to reach this purpose, the present invention uses following technical scheme：
A kind of telescopic LED screen based on set square, including some triangles being hinged pay unit, and the triangle is paid
Unit includes hinge, the set square being hinged and small flag plate, the hinge and sequentially passes through the set square and the penoncel
Flag plate；
The set square and the small flag plate are provided with unit pin joint, and the triangle is paid unit and is hinged by the unit
Point forms telescopic triangle and pays group.
More excellent, the small flag plate includes triangle substrate and extension rod, and the extension rod is located at the triangle substrate
One end, the three pin substrate are obtuse triangle plate, and the obtuse angle end is provided with the pin joint being hinged with the set square, described two
The one end of acute ends and the extension rod away from the triangle substrate is respectively equipped with unit pin joint.
More excellent, the set square is obtuse triangle plate, and the obtuse angle end of the set square is provided with and the small flag plate
Be hinged pin joint, the acute ends of the set square are respectively equipped with unit pin joint.
More excellent, three triangles pay the extensible basic system that unit forms ring-type.
More excellent, the triangle substrate is isosceles obtuse triangle.
More excellent, the set square is isosceles obtuse triangle.
More excellent, the LED board center-mount location is and adjacent described on the obtuse angle pin joint of the set square
LED board is superimposed when shrinking.
More excellent, the set square is molded for mould punching.
More excellent, the small flag plate is molded for mould punching.
More excellent, position of the hinge successively close to its corner edge from the set square and the small flag plate is worn
Cross.
The present invention's is effective：
1st, LED screen of the present invention is telescopic that is, screen can become big or diminish；
2nd, LED screen magnification can be very big, can reach screen area during contractions more than several times；
3rd, either amplify and reduce, its image is indeformable, i.e., the distance between LED is to amplify and reduce in proportion
's；
4th, flexible size of the invention is controllable, i.e. screen needs to reach how many times of stretching, extension, such as 2 times, 3 times, all
What can be quantified reaches；
5th, because the structure invented can shrink, so easy to carry and transport；
6th, manufacturing cost is low.

Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by specific embodiment mode.
A kind of telescopic LED screen based on set square, including some triangles being hinged pay unit 1, the triangle
Pay unit 1 and sequentially pass through the set square including hinge 11, the set square 12 being hinged and small flag plate 13, the hinge 11
12 and the small flag plate 13；The set square 12 and the small flag plate 13 are provided with unit pin joint, and the triangle pays unit 1
Telescopic triangle is formed by the unit pin joint and pays group.
As Figure 1-4, in one embodiment of the present of invention, the set square 12 and the small flag plate 13 are most basic
Element, it is hinged two-by-two by them and forms the triangle pair unit 1, it can be the set square 12 that triangle described in this example, which pays unit 1,
With the small flag plate 13 is be hinged is formed, or two small flag plates 13 are be hinged is formed, the set square 12 with it is described
The pin joint of small flag plate 13, the pin joint of the small flag plate 13 and the small flag plate 13 are center of rotation pin joint.
Further description, the small flag plate 13 include triangle substrate 131 and extension rod 132, the extension rod 132
Located at one end of the triangle substrate 131, the three pin substrate 131 is obtuse triangle plate, the obtuse angle end be provided with it is described
The be hinged pin joint of set square, the one end of two acute ends and the extension rod 132 away from the triangle substrate 131 is set respectively
There is unit pin joint.
